目前，大多數(shù)石化生產(chǎn)裝置都采用了DCS進(jìn)行控制，產(chǎn)生了較好的效益，但總的說來，DCS的應(yīng)用水平不高，其技術(shù)優(yōu)勢還遠(yuǎn)沒有完全發(fā)揮出來。據(jù)專家們估計(jì)，當(dāng)前我國企業(yè)對DCS的應(yīng)用能力普遍

解決這一問題的途徑是：一是要求FF在其國際標(biāo)準(zhǔn)中推出完善的用戶層和嚴(yán)格的互操作性的產(chǎn)品認(rèn)證；二是提高用戶抵制非國際標(biāo)準(zhǔn)的FCS的自覺性。工業(yè)以太網(wǎng)向FCS現(xiàn)場級的延伸。必須指出，工

 c、工業(yè)以太網(wǎng)的研究課題上述研究工作的進(jìn)展為以太網(wǎng)進(jìn)入FCS提供了可行性，但要使以太網(wǎng)能在FCS中發(fā)揮其強(qiáng)大的網(wǎng)絡(luò)優(yōu)勢，以滿足現(xiàn)代工業(yè)控制中日益增長的數(shù)據(jù)傳輸和信息傳輸

通常普通控制算法在現(xiàn)場控制器中進(jìn)行（可由上層控制器下載），而高級控制算法則在上層控制器中進(jìn)行，其控制輸出經(jīng)以太網(wǎng)集線器和以太網(wǎng)I/O接口傳輸?shù)浆F(xiàn)場執(zhí)行儀表。由于實(shí)時(shí)現(xiàn)場儀表掛接在專

 以太網(wǎng)具有傳輸速度高、低耗、易于安裝和兼容性好等方面的優(yōu)勢，由于它支持幾乎所有流行的網(wǎng)絡(luò)協(xié)議，所以在商業(yè)系統(tǒng)中被廣泛采用。但是傳統(tǒng)以太網(wǎng)采用總線式拓樸結(jié)構(gòu)和多路存取載波

現(xiàn)場總線傳輸特點(diǎn)現(xiàn)場總線控制系統(tǒng)（FCS）是順應(yīng)智能現(xiàn)場儀表而發(fā)展起來的。它的初衷是用數(shù)字通訊代替4－20mA模擬傳輸技術(shù)，但隨著現(xiàn)場總線技術(shù)與智能儀表管控一體化（儀表調(diào)校、控制組

FCS實(shí)現(xiàn)控制功能下移至現(xiàn)場層，使DCS的多層網(wǎng)絡(luò)被扁平化，各個(gè)現(xiàn)場設(shè)備節(jié)點(diǎn)的獨(dú)立功能得以加強(qiáng)，因此，在FCS中有必要增加和完善現(xiàn)場子層設(shè)備間的數(shù)據(jù)通訊功能。由于歷史的原因，DCS

然而，任何新事物的發(fā)生，發(fā)展都是在對舊事物的揚(yáng)棄中進(jìn)行的，F(xiàn)CS與DCS的關(guān)系必然也不例外。FCS代表潮流與發(fā)展方向，而DCS則代表傳統(tǒng)與成熟，也是獨(dú)具優(yōu)勢的事物。特別是現(xiàn)階段，F(xiàn)

 隨著電站汽輪機(jī)、燃汽輪機(jī)市場的逐步復(fù)蘇，新發(fā)電機(jī)組招標(biāo)和老機(jī)改造正在緊鑼密鼓的蓄勢待發(fā)。而基于我們輕車熟路的DEH控制系統(tǒng)卻逐步將被DCS系統(tǒng)所取代。我們的生存面臨著嚴(yán)
